TLL-500A
The TLL-500A is an energized conductor supporting tool that helps to create work clearances for Sub-Transmission work.
The Triple Line Lifter-500A fills the gap in our line of energized conductor manipulator lifters between the TLL-500 (which is used for distribution voltages) and the TLL-1300 (which is designed for transmission voltages from 115kV to 130kV). This gap is known in the utility industry as sub-transmission. Hence, the TLL-500A is designed for voltage ratings from 34.5kV to 72.5kV.

TLL 500A
The TLL-500A replaces the need for temporary structures and tag lines while giving positive control of distribution live lines. It consists of 4 major components: mast, crossarm, insulators and extension arms and breaks down into manageable sized components that can quickly and easily be installed in the field by 2 people. The TLL-500A is offered in Series 1 and 3. To clarify the differences, see the options below.
TLL-500A Series 1
- Voltage ratings: 34.5kV – 72.5kV
- Mounts to crane or digger derrick
- Mast turntable allows for 15° swivel left or right when the TLL-500A is in-line with the crane boom or perpendicular
- Converts from horizontal to vertical configuration
TLL-500A Series 3
- Same components as TLL-500A Series 1, except the pinning of the slider every 3” (76 mm) has been replaced with a cylinder for hydraulic extension and retraction
- Allows 30” of insulator travel
TLL-500A Skids
- Stores all the components of the TLL-500A
- Components are pinned to the structure of the skid
- Components are placed in order of assembly to make building/tearing down the unit easier
